Interactions between krill and its predators in the western Ross Sea

Frontiers in Marine Science
Krill is a fundamental resource in the pelagic food web of the Ross Sea, constituting an important link between primary production and top predators.

Hypoxia Tolerance of 10 Euphausiid Species in Relation to Vertical Temperature and Oxygen Gradients

Frontiers in Physiology, 2020
Oxygen Minimum Zones prevail in most of the world’s oceans and are particularly extensive in Eastern Boundary Upwelling Ecosystems such as the Humboldt and the Benguela upwelling systems.

Distribution and ecology of the four Macrourus species by‐caught in the longline fishery at South Georgia, Southern Ocean

Journal of Fish Biology, EarlyView.
Abstract Although Macrourus species are the main by‐catch across Southern Ocean longline fisheries, including around South Georgia, the lack of species‐specific data has hindered effective management and ecological understanding. Aggregation of macrourids at genus level masks critical interspecific differences in life‐history strategies and ...

Opportunistic Feeding and Parasite Assemblages in Sei Whales (Balaenoptera borealis) From Southern Chile Revealed by DNA Metabarcoding

Ecology and Evolution, Volume 16, Issue 10, October 2026.
This study represents the first metabarcoding‐based description of prey composition and parasite‐associated taxa in stranded sei whales from southern South America. ABSTRACT Balaenopterid whales are major consumers in pelagic ecosystems and play a fundamental role in marine food webs.

A study on the multi-frequency acoustic target strength of krill using a stochastic distorted-wave born approximation (SDWBA) model

Fisheries and Aquatic Sciences
We examined the dB difference in target strength at multiple frequencies (ΔTS) for the identification of Antarctic krill (Euphausia superba) and ice krill (Euphausia crystallorophias) using a stochastic distorted-wave Born approximation model.

Systematic sequencing of mRNA from the Antarctic krill (Euphausia superba) and first tissue specific transcriptional signature

BMC Genomics, 2008
Background Little is known about the genome sequences of Euphausiacea (krill) although these crustaceans are abundant components of the pelagic ecosystems in all oceans and used for aquaculture and pharmaceutical industry.

Nanomaterials' Multigenerational Effects by Single and Joint Exposure in Non‐mammalian Models

Environmental Toxicology, Volume 41, Issue 10, Page 957-974, October 2026.
ABSTRACT Nanotoxicology has mainly focused on single‐generation studies, leaving multigenerational toxicity underexplored. Having animal welfare recently gained importance, we aimed to provide the state‐of‐the‐art of knowledge about multigenerational effects in non‐mammalian models in the case of nanomaterials (NM) single and joint exposure to other ...

KrillDB: A de novo transcriptome database for the Antarctic krill (Euphausia superba).

PLoS ONE, 2017
Antarctic krill (Euphausia superba) is a key species in the Southern Ocean with an estimated biomass between 100 and 500 million tonnes. Changes in krill population viability would have catastrophic effect on the Antarctic ecosystem.

Variability in Overwinter Antarctic Krill Transport Pathways and Connectivity in the South‐West Atlantic Sector of the Southern Ocean

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Our study demonstrates that particles transported within sea ice are advected over substantially larger distances compared with those transported solely by ocean currents, indicating that sea ice dynamics play a dominant role in enhancing long‐range particle dispersal in the Southern Ocean relative to ocean‐only transport.

Trace element concentration in Antarctic krill reflecting their distribution in the Weddell Sea

Russian Journal of Earth Sciences, 2021
Distribution of Al, As, Cd, Co, Cu, Fe, Mn, Mo, Ni, Pb, Rb, and Zn in the main body parts and total samples of juvenile Antarctic krill Euphausia superba was examined in the northeastern Weddell Sea.
